    摘要: An improved process for catalytically dewaxing a hydrocarbon oil is disclosed. In this process the waxy oil is contacted in the presence of hydrogen with a dense zeolitic dewaxing catalyst associated with a nickel-tungsten hydrogenation component. The dewaxed oil has unexpectedly good stability and a low bromine number compared with prior-art processed oils. The process may be used to dewax crude oils, fuel oil fractions and lubricating oils.

    摘要: The present invention provides a process for modifying a crystalline aluminosilicate zeolite having a Constraint Index of from about to about 12 which comprises:a) steaming the as synthesized crystalline aluminosilicate zeolite containing organic template material to decompose at least a portion of said template material and to extract zeolitic aluminum; and,b) contacting the zeolite resulting from step (a) in the ammonium, alkali metal or hydrogen form with a dealuminizing agent which forms a water-soluble complex with aluminum to remove a further quantity of zeolitic aluminum therefrom.

    摘要: A lubricant dewaxing process which is useful with difficult feeds, especially highly waxy feeds having paraffin contents in excess of 25 weight percent or feeds with high nitrogen levels, employs two-step dewaxing in which the first stage is carried out under relatively mild conditions using a binder-free zeolite dewaxing catalyst to obtain extended catalyst cycle life between successive reactivations with a constant temperature for the duration of each dewaxing cycle. The second stage dewaxing is also carried out with a binder-free catalyst under conditions which maintain the target pour point for the product with a progressively increasing temperature during each dewaxing cycle. More than one preliminary dewaxing stage may be provided in order to reduce severity in each stage with mild conditions and constant temperature being maintained in the preliminary steps. Using this process, extended catalyst cycle lives may be obtained with difficult feeds.
